The posterior chapman point for the adrenal glands lies between the spinous and transverse processes of which vertebral levels?

• A. T11-T12
• B. T12-L1
• C. T10-T11
• D. T9-T10

Answer: (A)

Chapman reflex points map visceral organs to specific thoracic levels, and posterior points lie in the soft tissue between the spinous and transverse processes of the corresponding vertebrae. For the adrenal glands, the posterior Chapman point is located between the spinous and transverse processes at around the lower thoracic levels, specifically between T11 and T12. This positioning reflects the sympathetic pathways feeding the adrenals via thoracic splanchnic nerves that pass through that region, so stimulation there can influence adrenal function reflexively. Levels that are higher or lower relate to different organs or parts of the same region, not the adrenal glands.
